I have had a chance the last few days to look over some videos that various readers have sent me links to. Here is one that I think you find worth a look.
The video was taken in Rio Colorado, Rio Negro, Argentina, at 7:30 AM, January 12, 2001. It was shot with a mobile phone, but the quality is not that bad.
The videographer slowed down the footage several times to allow a better look. Check it out at UFO in Rio Colorado, Argentina, and comment if you wish.
